Which is a CORRECT statement regarding the 802.11n Wi-Fi standard?
A) It uses a single-path propagation approach.
B) The 802.11n AP can use both 2.4Ghz and 5Ghz bands simultaneously.
C) The 802.11n AP can combine channel 1 and channel 11 to form a bigger transmission channel.
D) With 802.11n, all frames are treated equally with the same priority in delivery.
E) Its bandwidth is about the same as the 802.11g standard.

Question

Quizplus · Accepted Answer

The 802.11n standard supports dual-band operation, allowing for simultaneous use of 2.4GHz and 5GHz frequency bands. This provides more flexibility in choosing the best available frequency band for data transmission. The other options are incorrect: A) 802.11n uses multiple-input multiple-output (MIMO) technology for better signal propagation, not single-path propagation. C) The 802.11n AP can combine two or more channels for greater bandwidth, but channel 1 and channel 11 cannot be combined because they are too far apart in frequency. D) 802.11n uses Quality of Service (QoS) to prioritize different types of frames for delivery, so they are not all treated equally. E) 802.11n has a higher bandwidth than 802.11g, typically offering up to 600 Mbps compared to 54 Mbps for 802.11g.
